[Figure 9] 4 is a flowchart showing a display procedure performed by the control system of FIG. 1. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Before describing the specific embodiment of the present disclosure, an overview of the embodiment will be described. The embodiment relates to a control system that displays information about each of a plurality of sensors installed in a facility such as a house. The plurality of sensors are, for example, fire alarms. The plurality of fire alarms are connected to a control device installed in the facility, and transmit alarm information to the control device when a fire is detected, and transmit malfunction information to the control device when a malfunction is detected. The plurality of fire alarms are also battery-powered, and transmit the remaining battery power to the control device. The control device is connected to a server outside the facility via a network, and transmits alarm information, malfunction information, and remaining battery power (hereinafter collectively referred to as "information") to the server. The server can be accessed from an information terminal device such as a smartphone.

[0011] The information terminal device or control device is a display device and is capable of displaying a plurality of pieces of information. For example, notifications for notifying alarm activation information and malfunction information are displayed. When the number of fire alarms increases, or when both fire alarm activation information and malfunction information are transmitted from one fire alarm, the number of displayed notifications increases. This makes it difficult for the user to recognize the information.

[0012] In order to easily recognize information about each of the multiple fire alarms, the display device according to this embodiment classifies the multiple fire alarms into one or more groups. The display device also displays an area (hereinafter referred to as the "first area") in which information representative of each group is displayed, and an area (hereinafter referred to as the "second area") in which information about each of the two or more fire alarms included in each group is displayed, on separate screens. When alarm information and malfunction information are received from two or more fire alarms included in a group, the display device selects one of the pieces of information based on priorities previously assigned to the various pieces of information, and displays a notification (hereinafter referred to as the "first notification") in the first area to notify the user that the selected information exists. The display device also displays a notification (hereinafter referred to as the "second notification") in the second area to individually notify the user that the alarm information and malfunction information have been received.

[0013] When the user finds the first notification on the screen including the first area, the user recognizes that among the multiple pieces of information in the group, there is information with a high priority. At this stage, the user does not recognize from which fire alarm the information is being received, or which other information is being received. Therefore, when the user finds the second notification on the screen including the second area for the group, the user recognizes, based on the second notification, the fire alarm that sent the information and the fire alarm that sent information other than the information in question.

[0014] 1 shows the configuration of a control system 1000. The control system 1000 includes a first representative fire alarm 200a and a second representative fire alarm 200b collectively referred to as a representative fire alarm 200, a first fire alarm 220a, a second fire alarm 220b, a third fire alarm 220c, and a fourth fire alarm 220d collectively referred to as a fire alarm 220, a control device 300, a router 400, a network 420, a server 440, and a mobile terminal device 500. Here, the number of representative fire alarms 200 is set to "2" and the number of fire alarms 220 is set to "4", but is not limited thereto.

[0015] The representative fire alarm 200 includes a detection unit 202, a control unit 204, and a communication unit 206. The control device 300 includes a first communication unit 310, a second communication unit 312, a memory unit 314, an operation unit 316, a display unit 318, and a processing unit 330, and the processing unit 330 includes an input unit 340 and a display control unit 342. The mobile terminal device 500 includes a communication unit 510, a memory unit 514, an operation unit 516, a display unit 518, and a processing unit 530, and the processing unit 530 includes an input unit 540 and a display control unit 542.

[0016] The representative fire alarm 200, the fire alarm 220, the control device 300, and the router 400 are installed in the facility 100, and the network 420 and the server 440 are installed outside the facility 100. The facility 100 is a building that is subject to control by the control system 1000, for example, a detached house. The facility 100 is not limited to a detached house, and may be a dwelling unit of an apartment building, an office building, a commercial facility, etc. In each of a plurality of rooms in the facility 100, the representative fire alarm 200 and the fire alarm 220 are installed as sensors for detecting the occurrence of a fire. The representative fire alarm 200 and the fire alarm 220 perform wireless communication with the control device 300. For example, a specific low-power radio is used as the wireless communication, but the present invention is not limited thereto, and wired communication may also be performed.

[0017] The wireless communication between the representative fire alarm 200, the fire alarm 220, and the control device 300 will now be described in more detail. The representative fire alarm 200 and the fire alarm 220 are classified into a first group 240a and a second group 240b collectively referred to as group 240. The first group 240a includes the first representative fire alarm 200a, the first fire alarm 220a, and the second fire alarm 220b, and the second group 240b includes the second representative fire alarm 200b, the third fire alarm 220c, and the fourth fire alarm 220d. In other words, one group includes one representative fire alarm 200 and one or more fire alarms 220.

[0018] The representative fire alarm device 200 performs wireless communication with the control device 300 by using a first frequency band such as the 926 MHz band, and also performs wireless communication with the fire alarm device 220 by using a second frequency band such as the 426 MHz band. On the other hand, the fire alarm device 220 performs wireless communication with the representative fire alarm device 200 by using the second frequency band such as the 426 MHz band, but does not perform wireless communication directly with the control device 300. Here, the fire alarm device 220 performs wireless communication with the control device 300 via the representative fire alarm device 200. Therefore, the representative fire alarm device 200 has a function of relaying wireless communication between the control device 300 and the fire alarm device 220, in addition to a function of performing wireless communication with the control device 300.

[0019] The difference between the representative fire alarm device 200 and the fire alarm device 220 is whether or not they have a relay function, and they have the same function of detecting fires, etc. Therefore, when explaining things other than wireless communication, the representative fire alarm device 200 may also be called the fire alarm device 220.

[0020] The representative fire alarm 200 is a sensor capable of detecting the occurrence of a fire in a room or the like of the facility 100. The detection unit 202 of the representative fire alarm 200 detects the occurrence of a fire by detecting smoke or heat. In the case of a smoke type that detects smoke, the occurrence of a fire is detected when smoke enters the representative fire alarm 200 and the light of the light-emitting diode is reflected by smoke particles and reaches the light-receiving unit. In the case of a heat type that detects heat, the occurrence of a fire is detected when the heat-sensitive element reaches a certain temperature. When the detection unit 202 detects the occurrence of a fire, the control unit 204 outputs a sound to notify the occurrence of the fire from a speaker (not shown) and generates alarm information to notify the occurrence of the fire. Here, the alarm information includes at least one of a fire occurrence and an operation test. The fire occurrence indicates the occurrence of a fire, and the operation test indicates a forced sound due to the operation test. The communication unit 206 transmits the alarm information to the control device 300 in the first frequency band. At that time, the communication unit 206 may transmit the alert information to the fire alarm 220 in the second frequency band.

[0021] The control unit 204 detects a malfunction or speaker disconnection in the representative fire alarm device 200. Known techniques may be used for these detections, and therefore a description thereof will be omitted here. The control unit 204 also has a timekeeping function, and measures the period since manufacture or the period since the last maintenance was performed. When the control unit 204 detects a malfunction or speaker disconnection, it generates malfunction information including a malfunction / disconnection indicating a malfunction or speaker disconnection, and when it detects the passage of 10 years, it generates malfunction information including the passage of 10 years indicating the passage of 10 years. The malfunction information may include the malfunction / disconnection and the passage of 10 years. The communication unit 206 transmits the malfunction information to the control device 300 in the first frequency band.

[0022] Furthermore, the detection unit 202 detects the remaining charge of the battery that drives the representative fire alarm device 200. Known technology may be used to detect the remaining charge of the battery, and so a description thereof will be omitted here. The remaining charge of the battery is indicated, for example, as 80% or 50%. When the remaining charge of the battery detected by the detection unit 202 changes, the control unit 204 causes the communication unit 206 to transmit the remaining charge of the battery to the control device 300 in the first frequency band. Here, the transmission of the remaining charge of the battery may be performed when the remaining charge of the battery changes by a predetermined amount, such as 5%, rather than every time the remaining charge of the battery changes.

[0023] The configuration of the fire alarm 220 is similar to that of the representative fire alarm 200, but the communication unit 206 (not shown) of the fire alarm 220 transmits alarm activation information, malfunction information, and remaining battery level in the second frequency band. The destination of the alarm activation information and malfunction information is the representative fire alarm 200, but may include other fire alarms 220. Also, the destination of the remaining battery level is the representative fire alarm 200.

[0024] As relay processing, when the communication section 206 of the representative fire alarm device 200 receives alarm information, malfunction information, and remaining battery level in the second frequency band from the fire alarm device 220, it transmits the alarm information, malfunction information, and remaining battery level in the first frequency band to the control device 300. Furthermore, when the representative fire alarm device 200 or the fire alarm device 220 receives alarm information including an occurrence of a fire, it may output a sound to notify of the occurrence of a fire from a speaker (not shown).

[0025] As described above, the first communication unit 310 of the control device 300 is compatible with, for example, a specific low power radio, and receives alarm information and malfunction information from the representative fire alarm device 200. The alarm information includes identification information (hereinafter referred to as "sensor identification information") for identifying the representative fire alarm device 200 or fire alarm device 220 that is the sender. The first communication unit 310 outputs the alarm information and malfunction information to the processing unit 330. The first communication unit 310 receives the remaining battery level from the representative fire alarm device 200. The remaining battery level also includes the sensor identification information. The first communication unit 310 outputs the remaining battery level to the processing unit 330.

[0026] The processing unit 330 stores the received alarm information, malfunction information, and remaining battery level in the memory unit 314. The memory unit 314 stores the alarm information, malfunction information, and remaining battery level for each sensor identification information. This corresponds to storing the alarm information, malfunction information, and remaining battery level for each sensor. FIG. 2 shows the data structure of the state table stored in the memory unit 314. It is registered in advance that the first group 240a includes the first representative fire alarm 200a, the first fire alarm 220a, and the second fire alarm 220b, and that the second group 240b includes the second representative fire alarm 200b, the third fire alarm 220c, and the fourth fire alarm 220d. The remaining battery level values ​​are shown for the representative fire alarm 200 and the fire alarm 220. When alarm information including a fire outbreak is received, "1" is shown in "fire outbreak". When alarm information including a fire outbreak is not received, "fire outbreak" is shown in "0". The same applies to the operation test in the alarm activation information, and the failure / disconnection and 10 years passed in the failure information. The date and time information indicates the date and time when the alarm was activated. The date and time information is generated by the representative fire alarm device 200 or the fire alarm device 220, and is included in the alarm activation information. Return to FIG. 1.

[0027] The processing unit 330 causes the first communication unit 310 to periodically transmit a confirmation signal for confirming the connection to each of the representative fire alarm device 200 and the fire alarm device 220. When the representative fire alarm device 200 and the fire alarm device 220 receive the confirmation signal, they transmit a response signal to the control device 300 indicating a response to the confirmation signal. The response signal also includes sensor identification information. Here, the transmission of the confirmation signal to the fire alarm device 220 and the reception of the response signal are performed via the representative fire alarm device 200.

[0028] When the first communication unit 310 of the control device 300 receives the response signal, it outputs the response signal to the processing unit 330. Through this processing, the processing unit 330 determines that communication is possible with the representative fire alarm device 200 or fire alarm device 220 that received a response signal to the confirmation signal. On the other hand, the processing unit 330 determines that communication is impossible with the representative fire alarm device 200 or fire alarm device 220 that does not receive a response signal to the confirmation signal for a certain period of time. The processing unit 330 stores communication status information indicating whether communication is possible or impossible for each sensor identification information. In the status table shown in FIG. 2, a "1" in "acquisition failed" of "communication status information" indicates that communication is impossible, and a "0" in "acquisition failed" of "communication status information" indicates that communication is possible.

[0029] Below, the screens that display information related to the representative fire alarm device 200 and the fire alarm device 220 will be explained in the order of (1) a screen displayed on the mobile terminal device 500, and (2) a screen displayed on the control device 300. In this embodiment, it is sufficient that at least one of these screens is displayed.

[0030] (1) Screen displayed on the mobile terminal device 500 The second communication unit 312 performs, for example, wireless communication or wired communication, and is connected to the server 440 via the router 400 and the network 420. For example, a wireless LAN (Local Area Network) is used as the wireless communication, but is not limited thereto. The second communication unit 312 transmits the changed information to the server 440 at the timing when any of the alarm information, failure information, communication state information, and battery remaining amount stored in the storage unit 314 changes. The information transmitted from the second communication unit 312 includes facility identification information for identifying the facility 100 in addition to the sensor identification information. When the server 440 receives the information, it stores any of the alarm information, failure information, communication state information, and battery remaining amount for each facility identification information and each sensor identification information. Through such processing, the state table of the server 440 is synchronized with the state table of the storage unit 314 after a predetermined delay.

[0031] The mobile terminal device 500 is, for example, a smartphone, a tablet terminal device, or a mobile phone device, and is used by a user residing in the facility 100. A communication unit 510 of the mobile terminal device 500 is connected to a server 440 via a network 420 by performing wireless communication. For example, a mobile phone system such as LTE (Long Term Evolution) or a wireless LAN is used as the wireless communication, but is not limited thereto. A storage unit 514 stores a program executable in the mobile terminal device 500, for example, an application program. In this embodiment, attention is focused on an application program (hereinafter referred to as a "control system application") that can execute processing in the control system 1000.

[0032] Operation unit 516 is, for example, a touch panel, and is capable of accepting operation input by a user. When operation unit 516 accepts operation input by a user, it outputs an operation signal corresponding to the operation input to processing unit 530. Display unit 518 displays a screen generated by display control unit 542. Display unit 518 may be configured integrally with operation unit 516, whereby display unit 518 displays a screen including buttons, and operation unit 516 accepts operation input when a user touches a button.

[0033] The processing unit 530 is configured, for example, by a microcomputer having a processor and a memory. The processor executes a program recorded in the storage unit 514, and various functions of the processing unit 530 are realized by the computer system. The processing unit 530 in this embodiment executes a control system application. The processing unit 530 transmits a signal for requesting a connection (hereinafter referred to as a "connection request signal") to the server 440 via the communication unit 510 and the network 420. The connection request signal includes identification information for identifying the mobile terminal device 500 (hereinafter referred to as "terminal identification information").

[0034] When the server 440 receives the connection request signal, the server 440 executes authentication processing based on the terminal identification information included in the connection request signal. If the authentication processing is successful, the server 440 permits connection with the mobile terminal device 500 and transmits a permission signal to the mobile terminal device 500 via the network 420. On the other hand, if the authentication processing is unsuccessful, the server 440 rejects connection with the mobile terminal device 500 and transmits a rejection signal to the mobile terminal device 500 via the network 420. If the server 440 permits connection, the server 440 transmits a status table to the mobile terminal device 500 via the network 420. After transmitting the status table, when the information included in the status table is updated, the server 440 sequentially transmits the updated information to the mobile terminal device 500 via the network 420.

[0035] Communication unit 510 of mobile terminal device 500 receives an approval signal or a rejection signal from server 440 via network 420. When an approval signal is received, communication unit 510 receives a status table from server 440 and sequentially receives information updated after the status table. When communication unit 510 receives a rejection signal, processing unit 530 ends the process, and when communication unit 510 receives an approval signal, processing unit 530 continues the process. When processing is to continue, processing unit 530 stores the status table received by communication unit 510 in storage unit 514. Subsequently, processing unit 530 updates the status table in storage unit 514 with the information sequentially received by communication unit 510.

[0036] The input unit 540 of the processing unit 530 receives information relating to each of the representative fire alarm device 200 and the fire alarm device 220 from the storage unit 514. The information is, for example, alarm activation information, malfunction information, communication status information, and remaining battery level, and the alarm activation information includes information on the date and time of alarm activation. The input unit 540 receives information sequentially whenever the information stored in the storage unit 514 is updated.

[0037] 3 shows the data structure of a table stored in the storage unit 514. As an example, a priority of "1" is assigned to a fire outbreak, a priority of "2" is assigned to an operational test, and a priority of "3" is assigned to a fault or disconnection. Furthermore, a priority of "4" is assigned to the passage of 10 years, and a priority of "1" is assigned to an acquisition failure. Here, priority "1" is the highest priority, and priority "5" is the lowest priority. Return to FIG. 2.

[0038] The display control unit 542 generates a screen for displaying the information received by the input unit 540 on the display unit 518. Here, Fig. 4(a)-(c) will be used to explain the screen generated by the display control unit 542. Fig. 4(a)-(c) show screens displayed on the display unit 518. Fig. 4(a) shows a screen showing representative information of each group, Fig. 4(b) shows a screen showing detailed information of one group, and Fig. 4(c) shows a timeline screen showing the history of information. When an area showing detailed information of one group is called a "first area 628", an area showing representative information of each group is called a "second area 626", and an area showing a timeline is called a "second area 630". Therefore, Fig. 4(a) corresponds to a screen including the first area 628, Fig. 4(b) corresponds to a screen including the second area 626, and Fig. 4(c) corresponds to a screen including the second area 630.

[0039] As shown in Fig. 4(a), the display control unit 542 generates a screen in the first region 628 such that the first portion 620 and the second portion 622 are included in the same screen. Specifically, the display control unit 542 generates a screen in which the first portion 620 and the second portion 622 are arranged vertically. The first portion 620 is a portion for displaying information related to the first group 240a, and the second portion 622 is a portion for displaying information related to the second group 240b. The display control unit 542 provides a first group display field 710 in the first portion 620, and displays the name of "Fire alarm 1", which is the first representative fire alarm 200a, a first message notification 642, and a first low battery notification 662 in the first group display field 710. Furthermore, the display control section 542 provides a second group display field 712 in the second section 622, and displays in the second group display field 712 the name of "fire alarm 2", which is the second representative fire alarm 200b, the first message notification 642, and the first low battery notification 662. Details of the representative information of the first group 240a and the representative information of the second group 240b, such as the first message notification 642 and the first low battery notification 662, will be described later.

[0040] When the user touches the display portion of "Fire alarm 1" in the first portion 620, the operation unit 516 receives an instruction to transition to a screen showing detailed information of the first group 240a. In response to this, the display control unit 542 generates a screen including the first portion 620 in the second area 626 as shown in FIG. 4(b). The display control unit 542 provides a first representative fire alarm display field 700, a first fire alarm display field 702, and a second fire alarm display field 704 in the first portion 620. The first representative fire alarm display field 700 shows the name of "Fire alarm 1" which is the first representative fire alarm 200a, and the first fire alarm display field 702 shows the name of "Living room fire alarm" which is the first fire alarm 220a. In addition, the second fire alarm display field 704 shows the name of "Dining room fire alarm" which is the second fire alarm 220b.

[0041] When at least one of the alarm information, the malfunction information, and the communication status information related to the first representative fire alarm 200a of the first group 240a is received, the display control unit 542 displays the second message notification 640 in the first representative fire alarm display field 700 of the first part 620. When at least one of the alarm information, the malfunction information, and the communication status information related to the first fire alarm 220a of the first group 240a is received, the display control unit 542 displays the second message notification 640 in the first fire alarm display field 702 of the first part 620. When at least one of the alarm information, the malfunction information, and the communication status information related to the second fire alarm 220b of the first group 240a is received, the display control unit 542 displays the second message notification 640 in the second fire alarm display field 704 of the first part 620. On the other hand, when all of the alarm information, the malfunction information, and the communication status information are not received, the display control unit 542 does not display the second message notification 640.

[0042] The second message notification 640 is a notification to notify that alarm information, malfunction information, and communication status information have been received for the corresponding representative fire alarm device 200 and fire alarm device 220, and the contents of the second message notification 640 are shown in "Message" in Fig. 3. For example, when the alarm information of a fire outbreak is received, the second message notification 640 is displayed as "Fire outbreak". In Fig. 4(b), the second message notification 640 in the first representative fire alarm display field 700 displays "Fire outbreak", so that the alarm information of a fire outbreak has been received for the first representative fire alarm 200a. Also, the second message notification 640 in the first fire alarm display field 702 displays "Failure / Speaker disconnection", so that the malfunction information of a malfunction / disconnection has been received for the first fire alarm 220a. Furthermore, the second message notification 640 in the second fire alarm display field 704 indicates "10 year elapsed notification," and therefore the malfunction information regarding the second fire alarm 220b that 10 years have passed is being accepted.

[0043] The display control unit 542 holds thresholds to be compared with the remaining battery level, for example, a first threshold and a second threshold (first threshold>second threshold). As an example, the first threshold is "20%" and the second threshold is "10%". When the remaining battery level is less than the first threshold and equal to or greater than the second threshold, the display control unit 542 determines that the battery is depleted, and when the remaining battery level is less than the second threshold, determines that the battery is dead. The display control unit 542 displays a second battery depletion notification (not shown) in the first section 620 for the representative fire alarm device 200 or fire alarm device 220 determined to be depleted, and displays a second battery depletion notification 660 in the first section 620 for the representative fire alarm device 200 or fire alarm device 220 determined to be depleted. The second battery depletion notification is a notification to notify the battery depletion, and the second battery depletion notification 660 is a notification to notify the battery depletion.

[0044] Here, because the remaining battery power of the first representative fire alarm 200a and the second fire alarm 220b is less than the second threshold value, the second low battery notification 660 is displayed in the first representative fire alarm display field 700 and the second fire alarm display field 704. On the other hand, because the remaining battery power of the first fire alarm 220a is equal to or greater than the first threshold value, the second low battery notification or the second low battery notification 660 is not displayed in the first fire alarm display field 702. The second low battery notification and the second low battery notification 660 are collectively referred to as the "second low battery notification," and the second low battery notification can be said to be a notification to inform the user that the remaining battery power is less than the threshold value.

[0045] When the user touches the display portion of "Fire alarm 2" in the second portion 622 in FIG. 4(a), the operation unit 516 receives an instruction to transition to a screen showing detailed information of the second group 240b. Although illustration of this screen is omitted, the display control unit 542 generates a screen similar to that in FIG. 4(b). In this screen, the second portion 622 is included in the second region 626, and the display control unit 542 provides a second representative fire alarm display field, a third fire alarm display field, and a fourth fire alarm display field in the second portion 622. In the second representative fire alarm display field, the name of "Fire alarm 2" which is the second representative fire alarm 200b is displayed, in the third fire alarm display field, the name of the third fire alarm 220c is displayed, and in the fourth fire alarm display field, the name of the fourth fire alarm 220d is displayed. Furthermore, the second message notification 640, the second low battery notification 660, and the like are displayed in the same manner as before.

[0046] In this way, the first portion 620 of the second region 626, the second portion 622 of the second region 626, and the first region 628 are included in different screens. In addition, a screen including the first region 628 can transition to a screen including the first portion 620 of the second region 626, and can also transition to a screen including the second portion 622 of the second region 626.

[0047] Returning to FIG. 4(a), the details of the representative information of the first group 240a will be described. When one or more second message notifications 640 are displayed in the first portion 620 of the second region 626 shown in FIG. 4(b), the display control unit 542 displays the first message notification 642 in the first group display field 710. On the other hand, when the display control unit 542 does not display the second message notification 640 in the first portion 620 of the second region 626 shown in FIG. 4(b), the display control unit 542 does not display the first message notification 642 in the first group display field 710. Here, the second message notification 640 is displayed in the first representative fire alarm display field 700, the first fire alarm display field 702, and the second fire alarm display field 704 in the first portion 620 of the second region 626, so that the first message notification 642 is displayed in the first group display field 710.

[0048] However, the contents of the second message notification 640 displayed in the first representative fire alarm display field 700, the first fire alarm display field 702, and the second fire alarm display field 704 in the first part 620 of the second area 626 are different. This corresponds to the fact that a fire has occurred, a malfunction / disconnection, and 10 years have passed have been accepted for the first representative fire alarm 200a and the fire alarm 220 included in the first group 240a. When the input unit 540 accepts a plurality of pieces of information, the display control unit 542 refers to the priorities shown in the table in FIG. 3 and selects the information with the highest priority. Here, the priority of the fire has a priority of "1", the priority of the malfunction / disconnection has a priority of "3", and the priority of 10 years has a priority of "4", so that the fire has been selected. The display control unit 542 displays the selected "fire has occurred" as the first message notification 642 in the first group display field 710 of the first part 620 in the first area 628 in FIG. 4(a). In other words, the first message notification 642 can be said to be a notification for notifying the presence of information with a higher priority when multiple pieces of information are received.

[0049] 4B, the display control unit 542 displays a first battery remaining notification for notifying the presence of one or more battery remaining notifications in the first group display field 710. When only the second low battery notification is displayed in the first portion 620 of the second area 626, the first group display field 710 displays the first low battery notification, and when only the second low battery notification 660 is displayed in the first portion 620 of the second area 626, the first group display field 710 displays the first low battery notification 662. In other words, the second battery remaining notification displayed in the first portion 620 of the second area 626 and the first battery remaining notification displayed in the first group display field 710 are the same.

[0050] For example, if the second low battery notification and the second low battery notification 660 are displayed in the first portion 620 of the second region 626, the first low battery notification 662 is displayed in the first group display field 710. On the other hand, if the display control unit 542 does not display one or more second battery remaining notifications in the first portion 620 of the second region 626, the display control unit 542 does not display the first low battery notification in the first group display field 710. Here, since the second low battery notification 660 is displayed in the first representative fire alarm display field 700 and the second fire alarm display field 704 in the first portion 620 of the second region 626, the first low battery notification 662 is displayed in the first group display field 710. The first message notification 642 and the second low battery notification that can be displayed in the first group display field 710 are representative information of the first group 240a. The representative information of the second group 240b is displayed in a second group display field 712, but since it is similar to the representative information of the first group 240a, a description thereof will be omitted here.

[0051] FIG. 4(c) shows a timeline screen generated by the display control unit 542. The timeline screen is a screen including the first portion 620 in the second area 630, and shows a history of information relating to the representative fire alarm 200 and one of the fire alarms 220. Here, as an example, a history of information relating to the first representative fire alarm 200a is shown. To such a timeline screen, transition is possible from a screen showing detailed information of one group, that is, a screen showing the second area 626 in FIG. 4(b). Moreover, transition to the timeline screen may be possible from a screen showing representative information of each group, that is, a screen showing the first area 628 in FIG. 4(a).

[0052] In the first portion 620 of the second area 630 in FIG. 4(c), all the second message notifications 644 related to the first representative fire alarm 200a are shown. Here, two second message notifications 644 are shown as an example. In the two second message notifications 644, "fire outbreak" and "10 years passed notification" are shown. This is as shown in FIG. 2. When the display control unit 542 receives two or more pieces of information related to the first representative fire alarm 200a, the display control unit 542 refers to the priority shown in the table in FIG. 3 and selects the information with the highest priority. In addition, the display control unit 542 displays a message corresponding to the selected information in the second message notification 640 in the first representative fire alarm display field 700 in FIG. 4(b). Furthermore, when the display control unit 542 judges that the first representative fire alarm 200a has a low battery or is out of battery, the display control unit 542 displays the history of the first representative fire alarm 200a judged in this way on the timeline screen.

[0053] The display control unit 542 also generates and displays a timeline screen similar to that of Fig. 4(c) for the first fire alarm 220a and the second fire alarm 220b included in the first group 240a. Furthermore, the display control unit 542 also generates and displays a timeline screen for the second representative fire alarm 200b, the third fire alarm 220c, and the fourth fire alarm 220d included in the second group 240b. The timeline screen is a screen including the second portion 622 in the second area 630, and is a screen showing the history of information relating to the representative fire alarm 200 and one of the fire alarms 220. Return to Fig. 1.

[0054] As described above, the representative fire alarm 200 communicates directly with the control device 300, but the fire alarm 220 communicates with the control device 300 via the representative fire alarm 200. Therefore, when communication in the representative fire alarm 200 becomes impossible, communication in the fire alarm 220 connected to the representative fire alarm 200 also becomes impossible. On the other hand, even when communication in the fire alarm 220 becomes impossible, the other fire alarms 220 and the representative fire alarm 200 are not affected. In other words, the influence of the representative fire alarm 200 becoming unable to communicate is greater than the influence of the fire alarm 220 becoming unable to communicate. Therefore, when the representative fire alarm 200 becomes unable to communicate, the display control unit 542 may display on the display unit 518 that communication with the representative fire alarm 200 is impossible, in addition to the display of "acquisition failed" in the first message notification 642 and the second message notification 640, or separately from these displays.

[0055] 5 shows another screen displayed on the display unit 518. Here, when the first representative fire alarm device 200a is not able to communicate, that is, when an acquisition failure for the first representative fire alarm device 200a is received, the display control unit 542 displays a message saying "Fire alarm 1 has gone offline." By seeing this message, the user can recognize that communication between the first representative fire alarm device 200a and the fire alarm 220 included in the first group 240a is not possible. Also, when the second representative fire alarm device 200b is not able to communicate, a similar message is displayed. Return to FIG. 1.

[0056] (2) Screen displayed on the control device 300 So far, a case has been described in which a screen showing information from various sensors is displayed on display unit 518 of mobile terminal device 500. Such a screen may be displayed on display unit 318 of control device 300. Although a screen longer in the vertical direction than in the horizontal direction has been assumed as the screen displayed on display unit 518, here, a screen longer in the horizontal direction than in the vertical direction is assumed as the screen displayed on display unit 318.

[0057] The input unit 340 executes the same process as the input unit 540. The storage unit 314 stores the same table as in FIG. 3. The display control unit 342 generates a screen for displaying the information received by the input unit 340 on the display unit 318. Here, to explain the screen generated by the display control unit 342, FIGS. 6(a)-(c) are used. FIGS. 6(a)-(c) show screens displayed on the display unit 318. FIG. 6(a) shows a screen showing representative information of each group, FIG. 6(b) shows a screen showing detailed information of one group, and FIG. 6(c) shows a timeline screen showing the history of information. That is, FIGS. 6(a)-(c) correspond to FIGS. 4(a)-(c), respectively, and FIG. 6(a) corresponds to a screen including the first region 628, FIG. 6(b) corresponds to a screen including the second region 626, and FIG. 6(c) corresponds to a screen including the second region 630.

[0058] 6(a), the display control unit 342 generates a screen such that the first portion 620 and the second portion 622 are included in the same screen in the first region 628. Specifically, the display control unit 542 generates a screen in which the first portion 620 and the second portion 622 are arranged horizontally. The provision of a first group display field 710 in the first portion 620 and a second group display field 712 in the second portion 622, and the display contents in the first group display field 710 and the second group display field 712 are similar to those in FIG. 4(a), and therefore will not be described here.

[0059] As shown in FIG. 6(b), the display control unit 342 generates a screen including the first portion 620 in the second region 626. The first representative fire alarm display field 700, the first fire alarm display field 702, and the second fire alarm display field 704 are provided in the first portion 620, and the contents of the display in the first representative fire alarm display field 700, the first fire alarm display field 702, and the second fire alarm display field 704 are the same as those in FIG. 4(b), so the description will be omitted here. As shown in FIG. 6(c), the display control unit 342 generates a history screen including the first portion 620 in the second region 630. The history screen may be transitionable from a screen showing representative information of each group, or a screen showing detailed information of one group. The contents of the display in the history screen are the same as those in FIG. 4(c), so the description will be omitted here.

[0060] The subject of the device, system, or method in the present disclosure includes a computer. The computer executes a program to realize the function of the subject of the device, system, or method in the present disclosure. The computer includes a processor that operates according to a program as a main hardware configuration. The type of the processor does not matter as long as it can realize the function by executing the program. The processor is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or an LSI (Large Scale Integration). The multiple electronic circuits may be integrated into one chip or may be provided on multiple chips. The multiple chips may be integrated into one device or may be provided on multiple devices. The program is recorded on a non-transitory recording medium such as a computer-readable ROM, an optical disk, or a hard disk drive. The program may be stored in the recording medium in advance, or may be supplied to the recording medium via a wide area communication network including the Internet.

[0061] The operation of the control system 1000 configured as above will be described. Fig. 7 is a sequence diagram showing a display procedure by the control system 1000. The control device 300 receives information (S10). The control device 300 transmits a status table to the server 440 (S12). The server 440 stores the status table (S14). The mobile terminal device 500 transmits a connection request signal to the server 440 (S16). The server 440 transmits the status table to the mobile terminal device 500 (S18). The mobile terminal device 500 receives the status table (S20). The mobile terminal device 500 selects information according to the priority (S22) and displays the selected information (S24).

[0062] 8 is a sequence diagram showing another display procedure by the control system 1000. The control device 300 receives information (S50). The control device 300 selects information according to priority (S52) and displays the selected information (S54). The control device 300 transmits a status table to the server 440 (S56). The server 440 stores the status table (S58).

[0063] 9 is a flowchart showing a display procedure by the control system 1000. The input unit 540 accepts information (S100). If multiple pieces of information have been accepted (Y in S102), the display control unit 542 selects information according to priority (S104) and displays the information on the display unit 518 (S106). If multiple pieces of information have not been accepted (N in S102), the display control unit 542 displays the information on the display unit 518 (S106).

[0064] According to this embodiment, when multiple pieces of information are received, the first message notification 642 is displayed to notify the presence of the information with a higher priority, so that when multiple pieces of information exist, the information can be easily recognized. Also, since the first message notification 642 is displayed in the first area 628, it can be easily recognized that the information is being received. Also, since the alarm information includes information on the date and time of the alarm, it is easy to identify the cause of the alarm. Also, since the alarm information has a higher priority than the failure information, when the alarm information and the failure information are received, the alarm information can be preferentially notified as the first message notification 642. Also, since the alarm information has a higher priority than the communication status information, when the alarm information and the communication status information are received, the alarm information can be preferentially notified as the first message notification 642.

[0065] In addition, since the second message notification 640 for notifying that the plurality of pieces of information have been received is displayed, the information regarding each of the plurality of sensors can be easily recognized. Furthermore, since the second message notification 640 is displayed in the second area 626 and the second area 630 for each of the plurality of pieces of information, the fact that the information has been received can be easily recognized. Furthermore, since the second battery remaining amount notification is displayed in the second area 626 and the second area 630 for each of one or more battery remaining amounts, and the first battery remaining amount notification is displayed in the first area 628, the fact that the battery remaining amount is less than the threshold can be easily recognized.

[0066] Furthermore, the fire alarms 220 and the representative fire alarms 200 are classified into a number of groups 240, and a first message notification 642 is displayed for each group 240, making it easy to recognize the information reception status of each group 240. Furthermore, the first part 620 of the first area 628 and the second part 622 of the first area 628 are included on the same screen, improving the visibility of the representative information of the first group 240a and the representative information of the second group 240b.

[0067] In addition, the second region 626, the first portion 620 of the second region 630, the second portion 622 of the second region 626, the second region 630, and the first region 628 are included in different screens, so that the information can be easily understood by dividing them. In addition, since it is possible to transition from a screen including the first region 628 to a screen including the second region 626, the first portion 620 of the second region 630, the relevance of the information can be easily recognized. In addition, since it is possible to transition from a screen including the first region 628 to a screen including the second region 626, the first portion 620 of the second region 630, the connection relationship between the first representative fire alarm 200a and the other fire alarms 220 can be easily recognized.

[0068] In addition, since it is possible to transition from a screen including the first region 628 to a screen including the second region 626 and the second portion 622 of the second region 630, the relevance of information can be easily recognized. In addition, since it is possible to transition from a screen including the first region 628 to a screen including the second region 626 and the second portion 622 of the second region 630, the connection relationship between the second representative fire alarm 200b and the other fire alarms 220 can be easily recognized.
